Human-Driven Microbiological Contamination of Benthic and Hyporheic Sediments of an Intermittent Peri-Urban River Assessed from MST and 16S rRNA Gene…
2017
International audience; Rivers are often challenged by fecal contaminations. The barrier effect of sediments against fecal bacteria was investigated through the use of a microbial source tracking (MST) toolbox, and by Next Generation Sequencing (NGS) of V5-V6 16S rRNA gene (rrs) sequences. Non-metric multi-dimensional scaling analysis of V5-V6 16S rRNA gene sequences differentiated bacteriomes according to their compartment of origin i.e., surface water against benthic and hyporheic sediments. Classification of these reads showed the most prevalent operating taxonomic units (OTU) to be allocated to Flavobacterium and Aquabacterium. Relative numbers of Gaiella, Haliangium, and Thermoleophilu…
Pursuing softer urban mobility behaviors through game-based apps
2020
Cities are currently engaged through their urban policies in pushing people towards less environmentally impacting mobility modalities: therefore, cycling and walking are strongly promoted, especially by means of new and wider limited traffic and no-cars zones. In this paper, the effectiveness of the new smartphones and apps-based technologies in modifying the mobility behaviors of citizens towards more sustainable choices has been investigated. Specifically, the potential of a smartphone app, directly involving citizens by means of a game rewarding the most sustainable trips, has been tested on a university commuters' group. These latter, starting from their current mobility situation, wer…
Reduced prevalence of soil-transmitted helminths and high frequency of protozoan infections in the surrounding urban area of Curitiba, Paraná, Brazil
2019
Human populations living in the surrounding urban areas of large Brazilian cities have increased vulnerability to intestinal parasites. However, the epidemiological scenario of soil-transmitted helminths (STH) in Curitiba, Paraná's main city, remains largely unknown. To bridge this gap of knowledge, this study aims to determine the prevalence of intestinal parasites and to investigate potential transmission pathways of the most prevalent species detected. We conducted a cross-sectional epidemiological study between July and September 2014 among schoolchildren in urban and peri-urban (deprived) areas of the municipality of Campo do Tenente, Curitiba. A total of 549 stool samples were used fo…
Early reductive stress and late onset overexpression of antioxidant enzymes in experimental myocardial infarction.
2020
Reductive stress is defined as a pathophysiological situation in which the cell becomes more reduced than in the normal, resting state. It represents a disturbance in the redox state that is harmful to biological systems. Our aim was to study the occurrence of reductive stress in the early phases of experimental myocardial infarction and to determine the mechanisms leading to such stress using a swine model. During the ischemic period, we found a decrease in the oxidized to reduced glutathione ratio (GSSG/GSH) (0.7-0.3), in the lactate to pyruvate ratio (42.7-132.4), in protein glutathionylation (111.8-96.1), and in p38 phosphorylation (0.9-0.4). This was accompanied by a significant increa…
Corticoperipheral neuromuscular disconnection in obstructive sleep apnoea.
2020
Abstract The roles of central nervous mechanisms and cortical output in obstructive sleep apnoea remain unclear. We addressed corticomuscular coupling between cortical sensorimotor areas and lower facial motor units as a mechanistic pathway and as a possible surrogate marker of corticoperipheral motor control in obstructive sleep apnoea. In this exploratory cross-sectional retrospective study, we analysed EEG (C3 and C4 leads) and chin EMG from polysomnography recordings in 86 participants (22 females; age range: 26–81 years): 27 with mild (respiratory disturbance index = 5–15 events/h), 21 with moderate (15–30 events/h) and 23 with severe obstructive sleep apnoea (>30 events/h) and 15 cont…
Menstrual dysfunction and body weight dissatisfaction among Finnish young athletes and non-athletes.
2020
To determine the prevalence of menstrual dysfunction (MD; i.e. oligomenorrhea or amenorrhea) and attitudes towards body weight among athletes and non‐athletes, we studied a cohort of athletes and non‐athletes, in adolescence (14–16 years) and subsequently in young adulthood (18–20 years). We further studied the differences between athletes reporting MD and eumenorrheic athletes at both time periods and identified physical and behavioural characteristicsthat might predict MD in young adulthood. Data were collected using questionnaires, accelerometers, and a pre‐participation screening. In adolescence, the athletes reported current primary amenorrhea more often than the non‐athletes (4.7% vs.…
Analysis of metacarpal V fractures of an interdisciplinary emergency room of an urban German hospital from a forensic viewpoint
2015
Metacarpal V fractures, especially metacarpal neck fractures, are known to the forensic society as a ‘boxer’s fracture’ and are described as being mostly caused by punching an immovable or firm object with force with a closed fist. To our knowledge there is no larger study that examines these fractures under forensic considerations of epidemiology. Our study includes the analysis of metacarpal V fractures in an interdisciplinary, academic and university-affiliated emergency department of an urban hospital over a period of three years. Emergency data sheets were systematically analysed and X-rays evaluated. The results were compared with the existing literature.
Inner Archipelagos in Sicily. From Culture-Based Development to Creativity-Oriented Evolution
2020
When Covid-19 arrived in Europe from the far East, the media and experts in economics and social sciences noticed that it was the expected discontinuity in the socio-economic development process. Really, the current phase has spread since the 1960s, when the application of econometric worldwide-spread development model was going to produce social inequalities, and consumption of physical, social, and cultural resources. Some places in Italy, far from the erosive and urban context and erosive metropolitan areas, are currently isolated seeds of a new cycle of life, because of the local community identity and the strong link between human, cultural, and natural components are currently working…
Comparing creative industries in Europe
2016
Creative industries are increasingly understood to contribute to localised innovation and dynamism. This paper provides a methodologically consistent comparison of creative industries across France, Great Britain, Italy and Spain. We map spatial agglomerations of creative activities showing evidence of urban concentration, which for Britain and France coincides with the dominance of capital cities, whilst for Spain and Italy, significant concentrations can also be found in secondary cities. The four countries also differ in the specialisation profiles and in the role played by policy makers. A lack of dove-tailing with the European Union smart agenda is argued to be a cause of concern.
Planification territoriale durable
2017
Au niveau local, la comprehension et le traitement des enjeux environnementaux necessite la mise en place d’approches de plus en plus transversales (pour la definition de strategies, la mise en œuvre de projets, etc.). Cela doit se traduire par un decloisonnement des politiques publiques, via une gestion moins verticale et plus integree des differentes competences de la collectivite. Dans ce contexte, on constate un besoin croissant de donnees de differentes natures, afin d’aider a la decision les pouvoirs publics et leurs parties prenantes, comme par exemple dans le cadre de projets de transformation urbaine. En parallele, on assiste a un elargissement exponentiel des possibilites offertes…
